It would be a big help if Bobby could get his anatomy straight. If someone were stupid enough to sit on a 30″ blade with a video chip on the tip, it MIGHT constitute a sigmoidoscopy, hardly a colonoscopy.

On the other hand, swallowing such a device, a time honored tradition albeit without the chip, MIGHT constitute an esophagoscopy. Needless to say, the latter is much safer than the former, the risk being comparable to an old-time rigid esophagoscopy.

It should be noted that the skills for performing these rigid procedures are rapidly passing away in favor of flexible fiberoptic examinations.
